I can't seem to find a tweak that will disable the "Carrier Settings Update" notification that appears every time I visit the "About" section under General Settings. It sometimes appears at random while in the home screen.

I use an iPhone 4, tethered 6.0.1, on baseband 4.11.08 that was unlocked during the SAM activation window back in April 2012. It is critical that I don't lose this unlock, so a tweak to disable this notification would be ideal.

I installed "No Update" in the modmyi repository, but that seems to affect only OTA firmware update notifications.

Back in April, did you call AT&T to get your phone factory unlocked? Your baseband is un-lockable unless its factory unlocked.

I dont think there's a tweak to prevent carrier update. As long as you don't update your baseband, you shouldn't have nothing to worry about.
